Panasonic BP-5917C40 - Overcharge Protection Circuits and Distribution Panels; General Information; Features; Specifications

Panasonic Solar Cells Handbook, Page 35 August 1998
11. OVERCHARGE PROTECTION CIRCUITS: DISTRIBUTION PANELS
Suitable for highly reliable power supplies
11.1. General Information
The "overcharge protection units" consists only of
overcharge protection circuits configured as a unit.
Being relatively low-cost, the unit is ideal for systems
which do not require testing.
These distribution panels distribute the power generated
by solar modules to storage batteries and loads. The
measuring circuitry provided makes it possible to test
the output current, output voltage, storage battery
voltage and load current of the solar modules. The
panels are also provided with overcharge prevention
circuits to protect the storage batteries from
overcharging.
11.2 Features
• Excellent reliability.
• Low current consumption.
• Lightweight
• Easy wiring and operation
